2020-07-05 13:22:18 -0600 | asked a question | How do I solve cos(2*t)==sin(t) I tried solving
I got
But this shouldn't be the value. I know from the graphs that the value is numeric. I have also noticed that sagemath is not good for solving trig identities. Is this true? |

2020-07-04 20:32:28 -0600 | asked a question | why doesn't sage solve ln I have a simple equation to solve
The actual value should be $x > e^2$ but sagemath gives
How do I get actual value? |

2020-07-04 12:49:23 -0600 | asked a question | why sagemath returns 2 solution instead of one when I run the expression
It returns
But I'm hoping that it would return
How do I get my expected value? |

2020-07-04 12:34:36 -0600 | asked a question | how do I test if a function is continuous Is there a way to test programmatically if a function is continuous? e.g $f(x) = \frac{1}{x} $ I'm looking for a function is_continuous(f) = False |

I'm trying to differentiate an implicit expression $x e^{y} = x -y$ This is my sagemath code Sagemath Answer is $\left( x, y \right) \ {\mapsto} \ \left(e^{y} - 1,\,x e^{y} + 1\right)$ But the actual answer is $\frac{1 - e^{y}}{x e^{y} + 1}$ How do I get the actual answer using sagemath? |
